Occasionally, KDE 4.8 will freeze and the frames and my windows will disappear. I have to restart X. This is what my .xsession_errors repeatedly says:
Code:
"/usr/bin/kactivitymanagerd(3117)" Soprano: "org.freedesktop.DBus.Error.ServiceUnknown - The name org.kde.nepomuk.services.nepomukstorage was not provided by any .service files"

I thought I turned off nepomuk indexing etc. Why is it still running? Is there a way to get rid of nepomukserver or permanently turn it off? Thanks
UPDATE: It appears that kdeinit4 crashes. Here's the backtrace:

I think the issue has to do with auto window tiling. I turned it off, and I'm not having these problems anymore.
